How do you keep docker/podman containers up-to-date? (self.selfhosted)

I used to simply use the 'latest' version tag, but that occasionally caused problems with breaking changes in major updates.

I'm currently using podman-compose and I manually update the release tags periodically, but the number of containers keeps increasing, so I'm not very happy with this solution. I do have a simple script which queries the Docker Hub API for tags, which makes it slightly easier to find out whether there are updates.

I imagine a solution with a nice UI for seeing if updates are available and possibly applying them to the relevant compose files. Does anything like this exist or is there a better solution?

Since my "homelab" is just that, a homelab, I'm comfortable with using :latest-tag on all my containers and just running docker-compose pull and docker-compose up -d once per week.

This is mostly my strategy too. Most of the time I don't have any issues, but occasionally I'll jump straight to a version with breaking changes. If I have time to fix I go find the patch notes and update my config, otherwise I just tag the older version and come back later.

I've recently been moving my containers from docker compose into pure ansible though since I can write roles/playbooks to push config files and cycle containers which previously required multiple actions on docker compose. It's also helped me to turn what used to be notes into actual code instead.

Just put all commands into a bash file. Starting with ‘’docker tag’’ changing tag to something else in case I need to revert and than pull, compose up. All run by crontab weekly. In case something breaks the latest working container is still there.
